The five basic processes of stamping are divided into blanking, bending, stretching, fine blanking and local forming.

1. blanking: the stamping process (including punching, blanking, trimming, cutting, etc.) that separates the sheets.

2. Bending: the stamping process of bending the sheet material into a certain angle and shape along the bending line.

3. deep drawing: a stamping process that changes a flat plate into various open hollow parts or further changes the shape and size of the hollow parts.

4. Fine blanking: the process of punching products with high precision, and products with high requirements on size and surface light quantity, which meet the requirements of drawings through fine blanking die.

5. local forming: a stamping process (including flanging, bulging, leveling and shaping) that changes the shape of a blank or stamping part with various local deformations.

application of stamping:

1. automobile manufacturing field: stamping has an important application in automobile manufacturing field. Large parts such as car body, door and roof often need to be formed by stamping process. Stamping process can quickly transform metal sheet into complex automobile parts with high efficiency, ensuring production efficiency and product quality. Stamping can not only achieve high-speed production, but also meet the diversified needs of automobile appearance.

2. field of household appliances manufacturing: stamping is also widely used in the field of household appliances manufacturing. Household appliances such as washing machines, refrigerators, microwave ovens and other key components such as the shell, door panels need to be formed by stamping technology. Stamping can improve production efficiency, accurately control product size and quality, and make household appliances have better appearance and function.

3. Electronic communication equipment manufacturing field: In the electronic communication equipment manufacturing field, stamping technology also plays an important role. Mobile phone housings and computer mainframe housings are all produced by stamping. Stamping can form various complex shapes and structures, and meet the requirements of electronic communication equipment for precision, lightness and beauty. Stamping can also be embedded with conductive parts, radiators and other functional components to improve the overall performance of electronic communication equipment.
